Two compact black network converters with dual SC ports and RJ45 jacks, paired with power adapters

BFKK

BFKK Multi-Mode Dual SC Gigabit Media Converter 2-pack 2km 850-1310nm

SKU CH-BH7A-KV89Y

A pair of multi-mode gigabit media converters linking RJ45 copper to dual SC fibre up to 2 km at 850-1310 nm

  • Extends copper links up to 2km via dual SC multimode fibre
  • Gigabit throughput at 1.25Gbps with 9K jumbo frame support
  • Auto-negotiating RJ45 ports handle 10/100/1000Base-T without manual setup
  • Operates reliably from 0°C to 60°C for industrial environments
  • Hot-swappable modular design with LED status for instant link monitoring

Dual SC Gigabit Media Converter Pair

This kit includes two multi-mode fibre converters that bridge a 10/100/1000Base-T RJ45 port to a 1000Base-SX SC slot. Each unit transports Ethernet at 1.25 Gbps over 850 nm multi-mode fibre up to 2 km, targeting installers who need to extend copper links across buildings or campuses.

Plug-and-Play Wall-Mount Installation

The converters are hot-swappable and require no software configuration; simply connect the fibre patch cords, plug the supplied 5 V DC adapters into AC 100–240 V mains, and link the RJ45 ports to switches or routers. Auto-negotiation and auto-MDIX handle speed and crossover automatically. Common issues arise when single-mode fibre is used by mistake or when patch cords exceed the 2 km multi-mode budget, causing link LEDs to stay dark.

Suits Campus Links, Not Single-Mode Runs

The pair suits network teams extending gigabit segments between cabinets or buildings where multi-mode cabling already exists. Buyers who need longer distances, single-mode compatibility, or managed features such as VLAN tagging and SNMP monitoring should look at different hardware.

Questions about this item

How can I confirm the media converter is operating correctly after connecting the cables?

The front-panel LEDs for TX, FX LINK/ACT, POWER and FDX light up to show link status, fibre activity, power presence and duplex mode, giving immediate visual confirmation that the 1.25Gbps connection is live.

What comes in the 2-pack and do I need to buy any cables or power supplies separately?

The box contains two multi-mode dual SC converters, two DC power adapters and one product manual; RJ45 patch cables and multi-mode fibre patch cords with SC connectors are not included and must be sourced separately.

Which wavelength option should I choose for a 2 km multi-mode run?

This model operates at 850-1310nm and is rated for up to 2km on multi-mode fibre, so the single supplied wavelength range covers the required distance without needing a different version.
